EEG acquisition in ultra-high static magnetic fields up to 9.4Â T

► EEG recording at ultra-high field up to 9.4 T is technically feasible. ► The cardiac-related artefact increases substantially between 7 T and 9.4 T. ► It is possible to retrieve auditory ERPs from data recorded in the 9.4 T field. ► ERSPs in alpha frequency are recorded in the 9.4 T field.
